A "SETV" cannot be gotten online as an American in Japan (screenshot proof attached). Later I will travel to Germany, it says I can get one online there. If I fly GERMANY -> PHILIPPINES (2 weeks) -> THAILAND with such a visa, will I be allowed entry? Or will they force me to fly direct from Germany to be allowed admission? Thank you.
TLDR : Answer Summary
An American traveling from Japan cannot apply for a SETV (Single Entry Tourist Visa) online due to restrictions; they must do so in person at Thai embassies. Once they reach Germany, however, they can apply online for the SETV. Concerns arise regarding whether flying from Germany to the Philippines and then to Thailand will affect entry requirements. The consensus among commenters suggests that as long as the visa is approved in Germany, the travel itinerary should be acceptable, but checking specific consulate requirements is advisable.
